Description

Technical Field

[0001] The utility model relates to the technical field of concrete curing boxes, and particularly relates to a curing box for curing all-desert-sand fiber-reinforced concrete. Background Technique

[0002] With the promotion of China's "Belt and Road" initiative, the infrastructure scale has been continuously expanding. As an indispensable material for building concrete, the demand for sand has increased sharply, and the contradiction with the increasing shortage of natural sand has become increasingly acute. At the same time, over-exploitation of natural resources and a large amount of carbon dioxide emissions from concrete production have led to a series of ecological problems. There are rich desert sand resources in the northwest region of China. If the desert sand is used as fine aggregate to prepare desert sand concrete by local materials, it can not only improve the shortage of natural sand, but also contribute to energy conservation and environmental protection.

[0003] Since the concrete prepared with desert sand as the main aggregate is in the research and test stage and the small-scale trial use stage, the prepared desert-sand fiber-reinforced concrete needs to be tested in many aspects. During the test process, the concrete curing box is an essential equipment. According to different curing methods, it can be divided into water curing boxes, steam curing boxes and electric heating curing boxes. Generally, the slightly hardened concrete blocks to be cured need to be placed on the internal shelves of the box, and the concrete is cured by means of heating, moisturizing or steam. However, during the curing and hardening process, there will be more or less concrete debris or dust on the shelves. The use requirements of the curing box require a high cleanliness inside the box to avoid polluting the concrete to be cured and causing deviation of test data. Therefore, those skilled in the art have proposed a curing box solution for curing all-desert-sand fiber-reinforced concrete again. Content of the Utility Model
